Vireo Alcaudón Pío Pteruthius flaviscapis

Stout medium-sized bird of foothill and montane forests. Endemic to Java, where it is the only “white-browed” shrike-babbler. Male is dark above and white below, with a bold yellow wing panel and bright white eyebrow. Female averages duller than the male, with grayish upperparts, olive-yellow wings, and a weaker white eyebrow. Hops about in the middle and upper levels of forest, gleaning prey from branches and leaf clusters. Sometimes with mixed flocks. Song is a bright but rather bland series of 3-5 notes: “wi-chew-chew” or “wi-chew-ba-chew-ba.”
